WHEEL AND DEMO'UNTABLE RIM.

Application filed Auguatlo, 1920. Serial No. 402,356.

This invention relates to improvements in vehicle wheels and has particular reference to improvements in wheels of the demountable rim type.

s The object'of my invention is to provide a wheel of the above mentioned ty e that is capable of carrying rims of different widths. In the service of the automobile wheel, it is often desired to use an ovensized tire and rim, which necessitatesthe substitution of a second wheel of the correct size, the felloe band on ordinary Wheels being made to fit correctly only one size of rim. My invention furnishes a construe tion by means of which such substitution may be accomplished without altering the wheel structure.

The above and other objects will more .fully appear from the following descrip- 2 tion and will be especially pointed out in the claims.

Fig. 1 is a transverse section through the felloe portion of a wheel, showing arim' of normal size afiixed. Fig. 2 is a similar view, but showing a lar er or over-size rim in place.

ig. 3 is a sectional view of another form of the invention showing an ordinary size rim in place. Fig. 4 is a similar view to Fig. 3, but

showing a larger or over-size rim.

In the drawings 10 represents the fired rim or felloe ofthe wheel which may be formed in any preferred manner. The tel- Ice is made with two parallel flanges, the outer one of which is designated by the numeral 11 and the inner one by the numeral 12. The outer edge of the flange 11 is formed with a beveled bearing surface or seat 13 for one side of the demountable rim 14. 1

The rim shown in this form of the invention illustrated in Fig. 1 and designated 14 is of the straight side type, being formed with two oppositely turned beveled ribs, the outer one being numbered 15, and the inner one 16. Between the beveled surface of the rib l5 and the seat 13 is interposed a wedge ring 17 which is forced into place by a number of clamping devices one of which is shown as a clamp plate 18 'l'ulcruming at 19 on the side of the wheel, being held into lace by a. nut 20 threaded on the; end of a bolt 21 which passes throu h the parallel flanges of thefelloe. A; su' icient number of bolts and clamps are located about the wheel to securely hold the rim.

Carried on the flange 12 is a supplemental bearing surface 22, said ring being angular in form, the body portion 23 fitting to the side of the felloe, it being firmly held in place by the bolts 21-, the angular flange 24 conforming to the configuration of the outer circumferential edge of the flange 12. The portion 24 of the ring 22 is formed with an inclined beveled surface 25 adapted to seat the rib 16 of the, demountable rim.

Referring to Fig. 2, it is seen that in order to accommodate a rim of greater width, it is necessary only to replace the ring 22 adapted to support the smaller size rim with a second ring 26. Like the ring 22, the ring 26 is singular in cross section, having a vertical portion 2'? and an in wardly extending flange 28, both of said flanges being adapted to fit closely on the flange "12. 29 designates the larger size rim? which is provided with ribs 30 and '31; similar to ribs 15 and 16. The rib' 30 is positioned by the wedge ring 17, the other rib 31 being seated on an inclined projeetion 32 'formed outwardly on the rim 26.

In Figs. 3 and {i I have illustrated another form of my invention. The wheel or fixed rim '33 is provided with the usual parallel flanges, the inner one being num bered 35 and the outer one 34, upon which is formed a beveled bearing seat 36 for one side of the demountable rim 14, the wedge ring 17 being interposed between the surface 36 and the inclined face of the rib 15 formed on the rim 14.. The circumference of the annular flange 35 is made witha fiat widened surface 37, and aflbeaded portion 38 at its edge. A ring 39'is adapted to be received on the surface 37, the ead such as an annular ring 33 limiting its lateral movement, said ring being constructed with a beveled seat upon which is seated the rib 16 of one side of the rim 14. p a

To accommodate-the larger size rim 29, :1 second ring 40 is substituted for the ring 39, which ring 4:0 is received on the seat 37 and protrudes outwardly further than the ring 39. It can easily be seen from an in spection of Figs. 3 andd that I may adapt thewhecl 33 to an ordinary or to an oversize rim without even removing the wheel from its place on an automobile.

It is obvious that the construction shown is sim .le, inexpensive, and very easily change it being 1' uired to replace the removable side ring o y when changing from one size to another., It does away with the necessity of providing wheels of difierent sizes to conform. with the use of regular or over-size tires.

' and still fall'within the scope of the invention.

I claim I p 1. in .a wheel construction, a fixed rim having bearing surfaces upon the peripheral edges thereof, one oi which is 'ialtwardly inclined, a demountable rim formed on its under sides with oppositely inclined marginal bearing surfaces, a removable wedge-shaped ring for engaging the inclined bearing sur faces of the rims, sald ring being transmea'eee versely adjustable, a removable annular ring having an inclined surface to engage the other bearing surface of the demountable rim, and means extending through the annular ring and the fixed rim to secure the rings in position, sa d means including a clamping plate fulrumed on one side of the fixed rim and adapted to engage the wedge-shaped ring.

2. In a wheel construction, a 'fixed rim havin peripheral flanges thereon, one of said fl anges bein inclined outwardly, a removable wedge-s iaped ring to engage the inclined flange of said rim, said ring being transversely adjustable, an annular ring surrounding the other flange, said annular ring having an inwardly inclined upper bearing surface, a demountable rim formed on its under sides ,with oppositely inclined marginal surfaces adapted to rest on the bear jngsurfaces-of said rings, bolts extending through the annular ring and the fixed rim, nuts threaded upon the bolts, and means upon the threaded'ends of the bolts for retaining the wedge-shaped ring in adjusted position.
